Sydney Airport opening times are:
T1 International terminal is opened everyday from 3AM to 11:00PM (0300 to 2300)
- Customs are opened for departures passenger processing at 4AM daily (0400)
T2 Domestic terminal is opened everyday from 4AM to 11:00PM (0400 to 2300)
There is a government mandated curfew operating at Sydney Airport between 11pm and 6am. For security reasons, the terminal is closed to the public overnight. During the times the airport is closed, there are a range of accommodation options on and off-airport from budget hotels to five-star establishments which may be booked online.
We do understand that there are occasions when passengers may be unable to obtain suitable accommodation, hence we provide a seated area near the train station at the international terminal. This area may only be accessed by those who have a valid ticket for a flight the following morning. As Sydney Airport is not a transit airport however, we do not encourage passengers to stay overnight.
